    <p>I have a Java EE application that is running on tomcat with a couple of entity classes and using eclipselink 2.1 and jpa 2.0. The entities are EmailNotification and EmailNotificationQueueRow.</p> <pre><code>@Entity public class EmailNotification implements Serializable, IEntity&lt;Integer&gt; { private static final long serialVersionUID = 1L; @Id @GeneratedValue(strategy = GenerationType.AUTO, generator = "emailGen") @SequenceGenerator(name = "emailGen", sequenceName = "SQ_EMAIL_NOTIFICATIONS", allocationSize=1) @Basic(optional = false) @Column(name = "EMAIL_ID") private Integer emailId; @Basic(optional = false) @Column(name = "EMAIL_SUBJECT") private String emailSubject; @Basic(optional = false) @Column(name = "EMAIL_BODY") private String emailBody; @Basic(optional = false) @Column(name = "SENT_FROM_EMAIL_ADDRESS") private String sentFromEmailAddress; @Column(name = "SEND_TO_ORG_ID") private Integer sendToOrgId; @Column(name = "SEND_TO_EMAIL_ADDRESS") private String sendToEmailAddress; @Column(name = "CARBON_COPY_ORG_ID") private Integer carbonCopyOrgId; @Column(name = "CARBON_COPY_EMAIL_ADDRESS") private String carbonCopyEmailAddress; @Column(name = "BCC_ORG_ID") private Integer bccOrgId; @Column(name = "BCC_EMAIL_ADDRESS") private String bccEmailAddress; @Column(name = "PROJECT_ID") private Integer projectId; //getters and setters } </code></pre> <hr> <pre><code>@Entity public class EmailNotificationQueueRow implements Serializable, IEntity&lt;Integer&gt; { private static final long serialVersionUID = 1L; @Id @Basic(optional = false) @Column(name = "EMAIL_QUEUE_ID") private Integer emailQueueId; @Basic(optional = false) @Column(name = "EMAIL_ID") private int emailId; @Basic(optional = false) @Column(name = "REQUEST_DATE") @Temporal(TemporalType.TIMESTAMP) private Date requestDate; @Basic(optional = false) @Column(name = "MESSAGE_SENT_FLAG") private String messageSentFlag; @Column(name = "MESSAGE_SENT_DATE") @Temporal(TemporalType.TIMESTAMP) private Date messageSentDate; @JoinColumn(name = "EMAIL_ID", referencedColumnName = "EMAIL_ID", updatable = false, insertable = false) @OneToOne(fetch = FetchType.LAZY) private EmailNotification emailNotification; //getters and setters } </code></pre> <p>Whenever I set the relationship of the emailNotification variable to FetchType.LAZY (as above) the class is not woven. It is registered for weaving but never is. </p> <p>The log is below. The EmailNotification entity is weaved but not the EmailNotificationQueueRow entity. Any ideas?</p> <pre><code>[EL Config]: 2011-02-15 14:21:13.642--ServerSession(1191324)--Thread(Thread[main,5,main]) --The access type for the persistent class [class persistence.model.EmailNotification] is set to [FIELD].

Also there are other OneToOne mappings that are lazy loaded in my project that get weaved. Its only this one class (EmailNotificationQueueRow) that doesn't get weaved.</p>

    1. COCan you try if setting ` nullable` on the JoinColumn or `optional` on the OneToOne to false changes anything? Also, which version of EclipseLink are you using?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
